Ignition switch did not solve
the problem with my IPC and HUD. I thought it had, as it was perfect for 200 miles and numerous test starts. So I placed the car for sale thinking it was now virtually flawless. This AM , out they went and it threw U1096 codes at me. Then they came on after a restart and then repeated the behavior. So it is intermittent. Restarting the car often reboots the IPC and HUD. They may stay on awhile, then go out, come back up for awhile, etc. All gauges go to 0. HUD is blank.
I was dumbfounded. Every ground plug, module plug, under seat plug and serial bus has been cleaned and checked for tang alignment. None showed any corrosion whatsoever, as this car has always been in climate control and shows no rust anywhere at 18,000 easy miles. Ignition switch is new. The car was checked and the IPC replaced by a dealer at 13K miles, battery is new and kept on tender and is always at full charge. Car starts and runs perfectly. All codes seem to be U1096 com codes. No vehicle performance issue codes.
Thinking back, it was the 1st owner who had the IPC replaced. It must not have solved the problem, so he, like I am now, probably got frustrated and he traded it for a C6. I bought it and have wrestled with this problem, thinking now, obviously incorrectly, that the ignition switch solved it.
I called my good friend and neighbor who is SV Mgr. with Hendricks, and he thinks we should throw a new BCM at it. There is no evidence of any water intrusion anywhere in the footwell or BCM area, for that matter, anywhere on the car.Or, perhaps, leave it on the RR tracks.
I sure can't sell it like this, and would feel real guilty dumping it on a trade to a dealer like the first guy seemingly did. In fact, my ethics wouldn't let me do that, and am down to living with it (at least it runs, rides and drives like a new vehicle) or to finding and fixing the elusive problem. I really want to fix it properly and ASAP so I can sell it with a clear conscience.
Any advice anyone?
Bill?
PS: the original switch contacts showed some black discoloration, but no pitting. Some were near perfect.
Thanks,
Dave

Want to add that
I am really good with mechanicals and replacements with guidance, but not with electrical stuff. Not so much with electrical schematics and test equipment. My go to local Vette guru says he cannot figure it out either. He, too, thought I had it fixed with the ignition switch. According to him, a bad hazard flasher would not cause this issue and the tails and signals work fine.
